I love this idea: duckdb.org/community_ex.... It translates dplyr syntax _inside_ of duckdb so you can mix it with regular SQL

Automated #SQL formatting within #rstats files has just been added to the `duckdb-r-editor` #positron extension. github.com/belian-earth... ✌️

I merged a PR for mirai today (fixing an esoteric bug), that came with a performance boost that I'd never have thought existed. That means that on my laptop, the default (with dispatcher) round-trip performance now dips into sub-100 microseconds territory!! Get it now: `pak::pak("r-lib/mirai")`

Hey #rstats fam, is anyone else having issues with the new Pandas update and reticulate? It's not converting the pandas DataFrames to R for me on AWS SageMaker and I can't quite pin down why.

Things are grim. But in more frivolous news... @jamesbrandecon.bsky.social and I have been chipping away at `dbreg`, a 📦 for running big regression models on database backends. For the right kinds of problems, the speed-ups are near magical. Website: grantmcdermott.com/dbreg/ #rstats [1/2]

{b32} is now on CRAN! Super speed base32 encoding & decoding compatible with tidyverse {blob} package (still 0️⃣ dependencies!) #rstats cran.r-project.org/web/packages...

a new #GDAL backend for xarray, coupled directly for Multidim *and* Classic raster (and actually works, pretty good improv this week) github.com/mdsumner/gdx Please try it out with your most|least favourite Zarr! If you have connection issues just ask I know enough to be dangerous #python

New release is more stable and should avoid annoying false positive linting errors. 👍

#rstats tidypolars 0.16.0 is available! tidypolars provides the tidyverse syntax while using polars for better perf. This release: - support for unnest and separate functions (tidyr) - new interface to export partitioned output - and more News: www.tidypolars.etiennebacher.com/news/#tidypo...

If you use #positron #rstats and #duckdb I'd love to know what you think of this: `duckdb-r-editor` a Positron extension for duckdb SQL code highlighting and completion within R files. github.com/belian-earth...

The latest release of #Positron has a TOTAL REVAMP of the integration to GitHub Copilot, which solves a ton of auth problems! In this screencast, I walk through how to set up Positron Assistant 🤖 to use GitHub Copilot as a model provider: youtu.be/T8dCQ6iIFXo

#Restoration is seen as the safer bet for #carbon finance. But it faces the same baseline challenge as avoided deforestation. Both require a defensible #counterfactual. We revisit a @science.org paper five years on. belian.earth/news/counter... www.science.org/doi/10.1126/... #forests

Nine volcanoes of Japan. Mt. Fuji is instantly recognisable. The others too, I hope. This took a while to get right. Looks like fancy chocolates, no? Or little LED buttons. #rayshader adventures, an #rstats tale

I released {secretbase} 1.1.0 today. github.com/shikokuchuo/... Adds optimized base58check and CBOR encoding. This is a zero-dep #rstats package that wraps C code for hashing and binary/text encoding often needed in web development contexts. It also handles the file/object hashing for {targets}.

#GDAL warp API works beautifully to deliver tiles to live website from arbitrary url (obvsly wmts and friends and cogs are best), configurable grid and crs, it's all there 🤷‍♂️ Using plumber2 and raw PNG bytes via VSIFile and vsimem, it's fab #rstats

2025 GDAL User Survey is now active for the entire month of December! Visit gdal.org/survey/ & tell the project how you use it, where you get help, what it should do in the future, & how/if it should use LLMs going forward. (optionally) give us your email, we'll even enter you to win a GDAL t-shirt!

just ran a Sentinel 2 query for every 100k grid square for March this year and pulled out unique instances there are 28696 unique grid codes

#GDAL just a friendly bump take a few minutes for the GDAL 2025 user survey to help focus GDAL Sponsorship Program activities. your opinions and feedback make a difference. Linked to from this issue, and there's also a link to last year's results: github.com/OSGeo/gdal/i...

Folks be sure take the #GDAL user survey for 2025, last year's brought a lot of improvements github.com/OSGeo/gdal/i... #rstats #python

heck yeah I know! github.com/mdsumner/est... been working on this a while and it's both an expanding cycle of virtue with years of work, and a near production ready science tool already ;)

One thing I appreciate about {targets} is the robustness of the pipeline: if I need to stop a long, compute-intensive process to run something else (or, in this case, I resize a pane and make the IDE crash🤷‍♂️), I don't need to worry about corrupted state: just restart R and tar_make() away! #RStats

I’m thrilled to share that my new book (Spatial Data Management with DuckDB) is now published! 🎉 At 430 pages, this book provides a practical, hands-on guide to scalable geospatial analytics and visualization using DuckDB. All code examples are open-source and freely available on GitHub.

The `enable_shiny_hover()` function in mapgl for #rstats lets you use your mouse's position as a Shiny input. Be judicious with how you use it... but it unlocks so many possibilities for mapping your data. Example: Census tracts that restyle based on your cursor position

Day 6 of the #30DayMapChallenge (3D), a render of Mount Rainier with a realistic atmospheric skydome generated w/ a lat/long/datetime, rendered entirely in #RStats with #rayshader and #rayrender! The atmosphere is annoyingly realistic: I now have to dial in the exposure depending on the time of day!

with{targets}, might seem that *your workflow* is complex and bespoke and not fit, you are probably wrong - it makes the expertise that is truly *yours* shine and grow. Encapsulate an entire production process and makes that easy to do it's more *you*, actually - keep at it! #rstats

Fantastic to welcome @trishg.bsky.social to the group today 🥳 Trisha is on an 1851 fellowship and will be working on resilience loss in savannahs with myself, @tommaso-jucker.bsky.social and @mdekauwe.bsky.social @bristolbiosci.bsky.social scholar.google.com/citations?us...

#rstats how do I make a target time-out, I want one in particular to only run every month or two there's a backlog of file urls, normal use is target_this_year, but every now and then I want the prior target_all_years to invalidate and do a full scan

I can see {targets} evolving past tar_assign to an actual new language syntax that's just R (its successor) I bet some are already thinking about this #rstats it's been an inexorable series of improvs and the foundation's so solid This is the edge, actual reproducibility and scaling

I'm guessing that R6 classes are implemented with environment shenanigans which is why base R plots can't be updated with class methods. Regardless, what's the best way to modify an existing plot within a method call? Is there a conventional pattern for passing the global environment or the like?

why tf does it suddenly work ...

Does targets::tar_cancel()/tarchetypes::tar_skip() not work with dynamic branching? I get "invalid 'description' argument" when downstream arguments depend on the cancelled target. My expectation would be that the cancellation would propagate to any downstream targets. #RStats

I recently added a Deepwiki badge to mirai.r-lib.org. Not because I think the current documentation is lacking 😅, but it takes you to an `Ask DeepWiki` prompt with the full mirai source code as context so you can ask questions (and get answers) in *any* language. Any feedback welcome! #rstats

hey spatial folks: if anyone has a great "parquet versus zarr" write-up, let me know. I'm never going to write a serializer but I'm really interested in the performance impacts of format for cloud downloads 👀 #geosky

I’m in the process of wiring a blog post (and @nacis.bsky.social talk) on using Python to drive GDAL. Has anyone tried this and been confused? If so, what tripped you up? Or if you’re an expert and have opinions, would you be willing to provide feedback? 🙏 #cartography #python #gdal

8 years old blog post, sad musing API being hidden under weaker downstream packages: www.hypertidy.org/posts/2017-0... so much has changed! I could write the same story but for R and Python now, good news though: {gdalraster}, duckdb, pyogrio, odc, mdim, and huge improvs in GDAL itself

Introducing {pmtiles}: an #rstats package to create, view, and interact with PMTiles. PMTiles is one of the most exciting geospatial innovations in recent years. Map tiles are stored & served from a single file, making massive geospatial data visualization widely accessible.
